Are you too cool for school? You might feel like that if you spend the night in an elementary school classroom converted into a hotel room. Of course, when it comes to cool, it's hard to beat the ice hotel in Sweden, which has to be kept at below freezing at all times.

For those looking for a little more depth in their travels, this mine-converted into a hotel suite is a whopping 500 feet below the surface.

If the puns are driving you crazy already, then you could always take a detour to the V8 hotel where life moves fast, but you're always in style.
